Automated platform tests should validate important user and integration behavior under representative roles. Isolate test data and cleanup.
Before you start
You should understand tables, records and the difference between client-side and server-side scripts. Work in a development instance with representative permissions. Identify execution scope, transaction timing and the current user before attributing behavior to a platform script or business rule.
The practical goal is to reason through this situation: A test submits a request and verifies approval and access behavior. Read the walkthrough first, then try the interview exercise before opening its answer. The important part is explaining the decision and its consequences, rather than remembering a definition alone.
Step-by-step walkthrough
Step 1: Choose critical user behavior
Verify a meaningful request transition and observable outcome.
Step 2: Run representative roles
Permissions can break ordinary users while administrator tests pass.
Step 3: Isolate data and dependencies
Know which external integrations the automated test really exercises.
Worked scenario
A test submits a request and verifies approval and access behavior.
A test submits a request as a requester, observes approval state and checks fulfillment permissions. A mocked external action establishes only the local contract; it does not prove the real remote system accepted the operation. Use separate integration evidence and reliable test-data cleanup where necessary.
Common mistake
A passing administrator-only form test does not prove ordinary users can complete the workflow.
Verify the behavior
Run under ordinary roles, verify denied paths and check cleanup after failed assertions.
Interview exercise
Select a release regression test.
Answer and reasoning
Cover the critical transition, permissions and observable result, then identify any external dependencies the test does not exercise.
